This week's
Steam Marketing Message mentions the two Valve nominees for the upcoming
Into the Pixel competition, and puts
out the word that the Half-Life 2: Episode 2 Orange Box is in "the home
stretch," as they've completed the developer commentary that will be part of the
coming release:

We're now in the home stretch on getting everything
finished off with the Orange Box games. Just this week, we've finished recording
and placing all of the developer commentary for the three new games. Episode
Two, Team Fortress 2, and Portal together will include over two and a half hours
of new commentary that should help shed some light into the thinking and
challenges behind these three new games. This is all in addition to the hour or
so of commentary included in Episode One. Commentary will be included on all
three platforms (PC, XBOX 360, and PS3).
